Abstract

The invention provides erythromycin enteric-coated tablets and a preparation method thereof. Each erythromycin enteric-coated tablet comprises a core, and an enteric coating and a sugar coating which wrap the core, wherein the core comprises effective therapeutic dose of erythromycin, corn starch, cassava starch, hydroxypropyl methylcellulose, hydroxypropylcellulose, carboxymethyl starch sodium and magnesium stearate; the enteric coating comprises polyacrylic resin II, ethanol, diethyl phthalate, castor oil and polysorbate-80; and the sugar coating comprises sucrose, talc powder, gelatin, white wax and dimeticone. The erythromycin enteric-coated tablets are stable and excellent in release degree, low in toxic or side effect and good in mouthfeel, and are stable in quality during storage; and the release degree of the tablets difficultly fluctuates together with prolonging of the storage time.

Description

technical field [0001] The invention belongs to an antibiotic drug and a preparation method thereof, in particular to an erythromycin enteric-coated preparation and a preparation method thereof. Background technique [0002] Erythromycin enteric-coated tablets are antibiotic drugs, suitable for mycoplasma pneumonia, neonatal conjunctivitis caused by Chlamydia trachomatis, infant pneumonia, genitourinary tract infection (including non-gonococcal urethritis), legionnaires' disease, diphtheria (adjuvant treatment) and diphtheria carriers, skin and soft tissue infections, whooping cough, respiratory infections (including pneumonia) caused by sensitive bacteria (influenza bacillus, pneumococcus, hemolytic streptococcus, staphylococcus, etc.), streptococcal angina, Listeria infection, rheumatism Long-term prevention of fever and prevention of endocarditis, Campylobacter jejuni enteritis, gonorrhea, syphilis, acne, etc. Because erythromycin is very sensitive to acidic media, it is...
